Determine whether the equation represents a direct variation. If it does, find the constant of variation. 2y=5x+1
2 answers:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In a direct variation the equation of the line passes through the origin
In this problem we have
----> this line not passes through the origin
therefore
<u>The answer is</u>
the equation does not represent a direct variation

We have been given that a rectangle has a height to width ratio of 3:4.5.
Let h be height and w be width of rectangle.
We can set our given information in an equation as:
Now we will substitute h=1 in this equation.
We can see that width of rectangle is 1.5 times height of rectangle.
Our one set of dimensions of rectangle will be: height=1 and width=1.5.
We can get many set of dimensions for our rectangle by multiplying both height and width of rectangle by same number.
Multiplying by 5 we will get our dimensions as: height 5 and width 7.5.
Therefore, (1 and 1.5) and (5 and 7.5) dimensions for rectangle will be scaled version of our rectangle.
